3 paź 2024 · In grain crops such as maize (Zea mays), leaf angle (LA) is a key agronomic trait affecting light interception and thus planting density and yield. Nitrogen (N) affects LA in plants, but we lack a good understanding of how N regulates LA. Here, we report that N deficiency enhanced lignin deposition in the ligular region of maize seedlings.
29 paź 2019 · Our study demonstrates a leaf segmentation approach based on a k-means algorithm coupled with an octree structure and the subsequent application of plane-fitting to estimate the leaf angle. Furthermore, the accuracy of the segmentation and leaf angle estimation was verified.
6 lis 2017 · Leaf angle, defined as the inclination between the leaf blade midrib and the stem, is one of the most important canopy architecture parameters that influence light interception, photosynthetic efficiency, and planting density.
22 gru 2022 · Leaf angle is an important agronomic trait determining maize planting density and light penetration into the canopy and contributes to the yield gain in modern maize hybrids [1]. The size of the leaf angle in plants is one of the important parameters affecting photosynthetic efficiency and canopy interception [2].
20 kwi 2023 · Diagram of leaf and solar angles. θl is the leaf inclination angle from horizontal, equivalent to the angle between the leaf normal and the zenith (the green arrow is the leaf normal); θs is the...
27 lut 2023 · Instead of measuring a single plant or selected leaves, the proposed method measures the angle of all the nonoccluded leaves and provides the leaf angle distribution throughout the canopy for the whole population.
10 cze 2021 · Here, we present TLSL e AF (Terrestrial Laser Scanning Leaf Angle Function), an automated open-source method of deriving LADs from terrestrial laser scanning. TLSL e AF produces canopy-scale leaf angle and LADs by relying on gridded laser scanning data.
